I went around with this several times myself when installing a general
error-message facility in our local C library, and came up with the
same answer: print the whole thing.  The only bad effect is that
occasionally someone will see more detail than needed.  Eliding all
but the `program name' part (on Unix, all but the last path component)
has the bad effect that occasionally someone will miss detail that
was needed (e.g., whether the error came from the new experimental
version of a program or the old known-buggy version or. . .).
